Day Six at The Miami Open has tennis fans at Crandon Park roaring with excitement. In men’s singles, we saw surprising matches from Nadal and Wawrinka. In the women’s matches we saw class acts from Radwanska, Halep, and Makarova.

Nadal retired during the third set against Damir Dzumhur of Bosnia-Herzegovina, 6-2, 4-6, 0-3. This is the first time Nadal retires since the 2010 Australian Open quarterfinals. The Miami Open is the only tournament Nadal has not won. The 29-year-old Spaniard is a four-time runner-up here (‘05, ‘08, ‘11, ‘14).

The first match at the Miami Open stadium was World no. 6 Kei Nishikori and French qualifier Pierre- Hugues Herbert. Nishikori beat Herbert 6-2, 7-6(4). He comes to The Miami Open after winning his fourth straight title in Memphis.

The World no. 4 Stan Wawrinka lost to Andrey Kuznetsov, 6-4, 6-3. Kuznetsov, the no. 2 Russian, is off to a career-best 10-5 start this year.

Canadian Milos Raonic advances to the third round after beating American Denis Kudla in two straight sets, 6(4)-7, 4-6. Raonic is the only Canadian remaining in the singles at The Miami Open.

Petra Kvitova, currently World no. 7, lost to fellow lefty Ekaterina Makarova 6-4, 6-4. "Of course it's always tough to play against a lefty… we're not used to it!" Makarova said. "Petra's such a great player, it was really tough to play against her. I'm just really happy I came through."

2012 Miami Open champion Agnieszka Radwanska defeated American Madison Brengle in two straight sets 6-3, 6-2. Radwanska advances to the third round and will compete against Bacsinszky or Ivanovic.

Simona Halep is still in the bidding for being the third person to win the BNP Paribas Open and The Miami Open back-to-back after beating Julia Goerges, 4-6, 1-6.

American Jack Sock advances after Sergiy Stakhovsky retired in the second set 6-2, 3-2. This is sock’s 4th Miami appearance and last year achieved his personal best in the third round.

In women’s doubles, Sloane Stephens (USA) and Madison Keys (USA) lost to Bethanie Mattek-Sands (USA) and Lucie Safarova (CZE), 4-6, 2-6. Stephens also lost in the singles division earlier this week to Heather Watson.
